EXPLOSIVE contro'srrron.

No Drawing. Original application filed June 18,1926, Serial No. 116,977.Divided and this application filed September ,9, 1926. Serial No.134,583.' i

My invention relates particularly to compositions containing anexplosive having one or more triazo groups and one or more nitrategroups, to compositions containing an explosive in which a hydrocarbonhas attached thereto one or more of each of said groups. p

a This application is a division of my copending application upon triazonitrate explosives and process of producing the same, Serial No.116,977, filed June 18,1926.

The object of my invention is to provide an explosive compositioncontaining a new type of explosive of the above character combining inpart the explosive groupings of two well-known high explosives, leadazide and nitroglycerine. Theobject of my invention is particularly toprovide compositions containing an explosive of this type in which oneor more triazo A N GH CH ONO I an explosive having greater strength andsensitiveness than nitroglycerine. I

While my'i'nvention is'capable of being carried out in many difierentways I shall describe only certain ways of carrying out thesame'lrereinafter.

The triazo nitrates as'above referred to may be made in any desired waybut, for example. they may be made by'treating a triazo alcohol withmixed acids. For instance, triazo-ethanol N,CH CH OH, the explosiveobtained therefrom will be triazo-ethanolnitrate N GH CH ONO thestructural formula of which is Again, in case a triazo polyhydricalcohol, as, for example, a triazo glycol, ismtrated,

but it has relation especially a in water.

considerably if the triazo alcohol to be "treated isdifferent kinds ofalcohols may be so treated in order to obtain the corresponding triazonitrates. In general, it will bebe prepared from the correspondinghalohydrins by any of the known methods of're-' placing the halogen bythe triazo group,- as, for exam'le, as described'by Forster and Fierz.in 1 Chem. Soc. (1908) 93-1865, re-- lating to the treatment of ethylenechlorohydrin with sodium azide.

In carrying out my invention, the explosives for use in compositionsmade in accordance with my invention may be made in any suitable waybut, for example, in the preparation of tria zo-ethanol-nitrate I mayadd one part by weight of triazo ethanol to two parts by weight. ofmixed acids comprising approximately 40% nitric acid and 60% sulphuricacid, either in the absence of nitrate formed collects on the surface ofthe waste acid and-may be drawn oii therefrom and washed repeatedlyuntil neutral, with such as a 5%,solution of sodium carbonate Thetriazo' -ethan'ol-nitrate ob tained is a colorless, neutral mobile 'oilhaving a specific gravity of about 1.3." It has greater sensitiveness tomechanical hock than nitroglycerine. as shown by the drop Weight method:Furthan nitroglycerine, as shown by the ballistic mortar test. r

, The triazo-ethanohnitrate as prepared I the aid of a weakly alkalinewater solution thermore, ithas a somewhat greater strength above is :ahigh explosive in itself and may beused in any desired type of explosivecomposition, for example, in combination with the usual ingredients ofdynamite to make a dynamite of great strength and sensitiveness. I

It may be used in adynamite comprising nitroglycerine" oritsequivalentfi with tetratinitrodiglycerine, nitro sugars or as, forexample, mixtures of nitroglycerine r nitroglycol. The followingcomposition may be cited as a specific example of a dynamite in whichthe new explosive may be used:

Parts by weight.

Triazo-ethanol-nitrate 15 Glycerine trinitrate 15 Sodium nitrate 57fWood meal 12 Cha1k 1 compound containing a triazo group and a nitrategroup.

It is also to be understood that any of the triazo nitrate explosivesmay be used in accordance with my invention as a substitute fornitroglycerine in any of the explosive compositions in which the latteris used, as, for example, in any ofthe known dynamite compositions. Forexample, such explosives.

other mineral fillers may be used instead of or together with the chalkferred to.

It is to be understood, however, that in all the above compositions theproportions hereinabove remay vary widely as to each and all of theingredients, according to the particular uses to which the explosive isto be applied.

While I have described my invention above in detail I Wish it to beunderstood that many changes may be made therein without departing fromthe spirit of the same.
